Disc battery ingestion in paediatric age

Acta Paediatrica, 2022
AbstractAimThe aim of the present study was to analyse clinical data of children referred for disc battery ingestion in order to assess short‐ and long‐term reported injuries and to identify outcome predictors and trends, define the urgency of intervention and refine treatment guidelines.MethodsThe records of all children admitted to Santobono ...

Versatile Battery Chargers for New Age Batteries

2011 International Symposium on Electronic System Design, 2011
This paper proposes two designs for a versatile charger capable of charging a range of batteries ranging from the conventional Li ion and Ni-Cd batteries to the more recent thin film batteries. The charger is equipped with a low power micro controller which enables the user to specify the kind of battery to be charged as well as calibrate the current ...

Understanding Battery Aging Mechanisms

2019
The aging mechanisms of Li-ion batteries are introduced in this chapter, and are experimentally investigated and modeled. From SEM it is found that the thickness of the solid electrolyte interface layers at the graphite electrode surface increase upon aging. Deformation of the graphite structure is confirmed by Raman spectroscopy.

Battery Aging, Battery Charging and the Kinetic Battery Model: A First Exploration

2017
Rechargeable batteries are omnipresent and will be used more and more, for instance for wearables devices, electric vehicles or domestic energy storage. However, batteries can deliver power only for a limited time span. They slowly degrade with every charge-discharge cycle. This degradation needs to be taken into account when considering the battery in

VRLA battery aging characteristics

Proceedings of Intelec'96 - International Telecommunications Energy Conference, 2002
In the framework of an extended test program to better understand the behavior of valve-regulated lead-acid (VRLA) batteries under various operating conditions, FIAMM reports on a comparison of thermal runaway tests carried out on two different 48 V batteries. This testing involved both new and five-year field-aged cells taken from a telecommunications

Ageing of rechargeable lithium batteries

Journal of Power Sources, 1985
Abstract Ageing of secondary lithium button cells is reported for two cases: cycling and storage. In respect of cycling, 120 deep cycles have been achieved with LiAl/dioxolane — LiClO4/NiPS3 cells; the rate of ageing is related to both the charge cut-off potential and the nature of the cathodic material. After storage at room temperature for one year

Battery Degradation and Ageing

2001
Batteries are subject to degradation in storage due to a variety of chemical mechanisms, such as limited thermal stability of materials in storage, e.g. silver oxide in silver - zinc batteries, or corrosion of metal electrodes, e.g. lead in lead - acid batteries or lithium in lithium / thionyl chloride batteries.

Aging of lithium-ion batteries

Journal of Power Sources, 2004
Abstract Lithium-Ion (liquid electrolyte) batteries are considered as long life and reliable systems. This paper: • introduces discussion about aging and degradation mechanism both for storage and cycling, • illustrates the proposed phenomena from results based on several years experimentation and obtained on scale one cells, •

Calendar aging of silicon-containing batteries

Nature Energy, 2021
High-energy batteries for automotive applications require cells to endure well over a decade of constant use, making their long-term stability paramount. This is particularly challenging for emerging cell chemistries containing silicon, for which extended testing information is scarce.
